The printed word is dying, but the printed keyboard is alive and kicking. And no, you won’t need a 3D printer to make one. A company called Novalia has made an incredibly thin Bluetooth keyboard made of photo paper, conductive ink and its proprietary electronic module.Nordic Semiconductor’s system-on-a-chip and a printing process that allows conventional printers to mass produce capacitive sensors.
I’m not sure if Novalia will make the keyboard available to the public. It does have Switchboard, a much simpler version of the keyboard on its online shop . That one’s made of foam board and has eight capacitive keys and sells for £25 (~$41 USD)
